TS4995EIJT

An audio power amplifier capable of delivering 1.2 W of continuous RMS output power into an 8 Ω load at 5 V. Thanks to its differential inputs, it exhibits outstanding noise immunity. An external standby mode control reduces the supply current to less than 10 nA. A STBY MODE pin allows the standby pin to be active high or low. An internal thermal shutdown protection is also provided, making the device capable of sustaining short-circuits. The amplifier features an internal fixed gain at 6dB which reduces the number of external components on the application board. The device is equipped with common mode feedback circuitry allowing outputs to be always biased at VCC/2 regardless of the input common mode voltage. The amplifier is specifically designed for high quality audio applications such as mobile phones and requires few external components.
